1. What is PMIC in EV?
The role of PMIC (Power Management Integrated Circuit) in electric vehicles (EV) is to manage and distribute power in electronic devices to ensure efficient and safe operation of batteries.
Basic definition and functions of PMIC
PMIC is a key component dedicated to managing and distributing power in electronic devices. It provides stable power to electronic devices and manages and controls batteries by integrating multiple power management functions, including power supply, battery management, charging management, and power consumption management. In electric vehicles, PMIC is responsible for charging, protecting and status monitoring of batteries, and intelligently managing battery health and life.

2. What is the power efficiency of PMIC?
The power efficiency of PMIC (power management integrated circuit) is usually above 90%. The main function of PMIC is to efficiently manage power and achieve high efficiency through switching converters, which can usually reach more than 90%.
Working principle of PMIC and factors affecting efficiency
PMIC works through switching converters to regulate voltage and current by controlling the opening and closing of switches. Increasing the switching frequency can significantly reduce switching losses, thereby improving efficiency. In addition, the high integration of PMIC makes multi-power application scenarios more efficient and smaller in size.
Efficiency differences between different types of PMIC
Different types of PMIC have different efficiencies. For example, LTC3892EUH-2 is a high-performance, dual-channel step-down DC/DC switching regulator controller with very high efficiency and suitable for various applications. LTC7803 is a high-performance synchronous step-down DC/DC switching regulator controller with 100% duty cycle capability, which also has the characteristics of high efficiency.
In summary, the power efficiency of PMIC is generally high, usually above 90%, and the specific efficiency depends on the design and application scenario of PMIC.

3. What is the difference between PMU and PMIC?
PMU and PMIC have significant differences in application scenarios and functional positioning.
Application scenarios
PMU: Mainly used in portable devices such as mobile phones, MP4, GPS, PDA, etc. It is a highly integrated power management solution that integrates traditional discrete power management chips (such as low-dropout linear regulator LDO, DC/DC converter DC/DC) to achieve higher power conversion efficiency and lower power consumption.
PMIC: usually refers to an external power management chip, which is used for system-level power management. A SOC (system on chip) usually requires multiple PMICs to provide multiple power supplies or high currents to meet the different requirements of different components for voltage, current, and frequency.
Functional positioning
PMU: Inside the SOC, as a power management unit, it is responsible for managing the power distribution and conversion inside the SOC to ensure the normal operation of each component. PMU sets control signals through control registers to achieve real-time software management.
PMIC: Outside the SOC, as an independent power management chip, it provides multiple power supplies and high current outputs to meet the different power requirements of the SOC. PMIC works with PMU to ensure the stable operation of the entire system.
